Exhaust Gas Boiler (EGB)

Every system, which is operated at high temperature, always has a risk of fire. This applies to EGB which has the inlet temperature of exhaust gases @ 300-400 deg. C. The most common type of Exhaust Gas Boiler (EGB) used on ships are water tube boilers.

In water tube type of arrangement, the water passes through tube stack, which is arranged in the path of exhaust gas inside the exhaust gas trunking of the main engine. The exhaust gas flows over the tube stacks and heats the water, thus producing steam.
